BM banned and no email field is present

Hello,
have you seen this type of bug before? It's the first time I see it.

Setup - 2 accounts attached to a verified BM

On the appeal step for entering an email, that email field is missing completely. Only two buttons are present Cancel and Send login code. When I click on send login code, no emails are received to the default email address added to the BM.

From the FB support, they say it's the first time they see this bug, but of course they cannot do anything about it - they say to try with another browser (I did - it's the same) or wait for a few days (this happened today, so I will see how it is after 24-48 hours).

My question is whether someone has seen this bug before and if yes, how did you appeal the BM?

Thanks!

Update:
It turns out that one of the accounts attached to the BM was with poor quality and all the other accounts are getting the same error when attached to the BM.

So, always use HQ accounts for your BMs.
